Question 19 is based on the passage you have just heard.

听力原文

        People spend a lot of time using phones and computers. Much of that time is devoted to text messages and social media. But many people choose to spend their time playing computer games. For years, parents and teachers have worried that these games might be addictive. (19) [And now the World Health Organization has recognized addiction to computer games as a disease.] The organization explains that this decision reflects general agreement among experts around the world that some people have a problem with these games. They show a pattern of behavior characterized by a lack of control. (20) [Such people make computer games a priority over their responsibilities. They may play games instead of attending school or work or socializing.] According to the World Health Organization experts, people’s use of computer games is different from their use of the Internet, social media and online shopping. These experts claim there is not sufficient data to indicate that people’s reliance on those other activities is an addiction. But they argue that playing computer games to excess is different. This behavior can become a disorder. To meet the new definition for addiction, the behavior must damage a person’s relationships or performance at school or work. And this must last for at least a year. Still, not all behavior experts agree. (21) [Some argue that there is not enough research on the subject. Thus, they claim it is too early to call computer game addiction a disorder.]

19. What conclusion has the World Health Organization come to recently?（世界卫生组织最近得出了什么结论？）

解析：C。录音中提到，现在世界卫生组织已经将电脑游戏成瘾定义为一种疾病。C项中的Addiction to computer games和a disease为原词复现，故C项正确。

错项排除：A项利用录音中出现的social media、addiction和disorder进行拼凑，故排除。录音开头说到，人们花了很多时间使用电话和电脑，但世界卫生组织的结论是关于人们对电脑游戏的上瘾而非手机，故B项错误。录音中提到很多人对电脑上瘾，但电脑游戏很容易上瘾并非世界卫生组织的结论，故D项错误。
